Description

'New description: 【New technology field】 This creation is about a transmission # moving device. ~ And, especially a two-cylinder four-piston transmission [prior art] heat engine or % engine's through the combustion of the fuel as heat, and then through the thermal cycle (such as the ring (external combustion engine), the heat into Machinery: Photographs) or Sterling Xunfan 'Don • Moonlight's mechanical structure' is used to listen to a warehouse. (After paying 1 2 BC 18QG years, heat engines are widely used in automobile locomotive buses, ships and The various traffic of the aircraft leads to the field of air compressors. Since the current agricultural machinery, weeding machines, and co2 greenhouse gases will be generated after the winding, f, the amount of fossil fuel used in the impact of fossil fuels is affected by the increase of 3 petrochemicals. The use of fuel 'avoids the increase of fuel: the discharge of the body. Therefore, in order to achieve this, the global researchers are trying to find the ideal mechanism to improve the efficiency of the heat engine. 烨撼, from 1860=代代' Whether it is a coal-powered steam engine (external second, Sterling engine powered by biomass energy (external combustion engine), or: oil-driven engine (internal combustion engine), mostly reciprocating式."匕母早独汽汽Department, corresponding to the individual - group of live, far r and curved rod touch, and then through the correction force _ called side step Wei, bribe t M437892 reciprocating mechanism action, like (top dead center) to receive the punch in the end (bottom stop = hand The punching action 'must punch out to the top and this kind of _ ^ ^ come out punch (reciprocating movement). To carry out multiple sets of live two-two sets of pistons, so if the number of consecutive points is added, because of the number of Cylinders, in order to increase the force, must 1 one if others want to increase the speed of the heat engine or twist the different hearts (four), the group of slaves, pistons, connecting rods and curved rod mechanism, ° 'connected or parallel, such as the common inline, v type, star type,

Giant opposites and other combinations. Although this combination can increase the heat engine = output efficiency month, it also causes the size, size, size, and weight of the heat engine to increase the load weight of the heater. As a result, the heat engine performance is not as good as expected. Take the four-cylinder four-piston module as an example. For example, the Inlme-four or Straight_f〇ur system arranges the cylinder and the piston along the longitudinal axis of the crankshaft.

Another four-cylinder four-piston module is arranged in a horizontally inverted (horizonally opposed 4) plane (left and right) arrangement, such as the common Flat-4 engine, although the above-mentioned straight four-cylinder is changed to a horizontal two-cylinder. The parallel arrangement of the horizontal two cylinders is added, but there is no change in the size of the three-dimensional (length, width, height) X, γ, and z dimensions. In addition, there is a cross arrangement in which the vertical direction of the in-line four-cylinder is combined with the horizontal direction of the horizontal reversal, but this design also cannot reduce the installation space, because there is an independent space requirement between the modules, so For inline, row, or cross arrangement that is not in the same straight line, there must be four times the space of the single-module on the mechanism space 4 M437892, in order to complete the assembly and movement of the mechanism. When k twelve pistons, the volume, size, size and weight of the i body will be greatly increased, resulting in a decrease in the source conversion efficiency of the heat engine.
